Work through the symptom that matches what you are seeing.

Tier features are locked straight after installing

No valid key was saved. Confirm LICENSE_KEY and LICENSE_SERVER_URL are both set in your .env file, with no stray spaces or quotation marks, then reload the admin portal.

License shows "suspended"

An invoice is overdue. Settle it and the next license check restores your features automatically — there is nothing else to do on your side.

License shows "expired"

The license term has ended. Renewal invoices are generated automatically before the due date, so check for an unpaid renewal invoice in your account on the vendor portal.

"Unable to verify license"

Your install cannot reach the license server. Check each of these:

• LICENSE_SERVER_URL is spelled correctly and includes https://.
• The curl PHP extension is installed and enabled — run php -m | grep curl.
• Outbound HTTPS is not blocked by a firewall. Test directly from the server:

curl -I https://my.whmaz.com

Remember that cached access is honoured for up to seven days, so you have time to resolve a network problem before features degrade.

Still stuck

Open a support ticket and include your license key, the exact error text, and your PHP version. That is usually enough to identify the cause on the first reply.
